Research at XM-1
The current research activities utilize specific features of full-field soft X-ray transmission microscopy
- elemental specificity of x-ray absorption
- high lateral resolution (currently down to 15nm) provided by Fresnel zone plates as optical elements
- large field of view of 15-20μm for a single image, which can be tiled up to even larger images
- recording images in varying external environments (magnetic fields, temperatures)
- sub-ns temporal resolution utilizing the pulsed time structure of the storage ring in a stroboscopic pump-probe scheme
- magnetic phase contrats imaging
Therefore XM-1 is used to image at high spatial and temporal resolution microscopic structures with
applications to magnetism, materials and environmental
science and biology.
Typical scientific topics include
Magnetism
- spin current induced domain wall motion
- spin torque induced dynamics
- stochastical character of nucleation
processes
- microscopic magnetization reversal behaviour
in pattermed media
- fast magnetization dynamics in patterned elements
Materials science
- electromigration processes and void
formation in interconnects
- imaging of Malaria
infected blood cells
- 3D imaging of cell structures with x-ray
tomography
- phase sensitive Fourier optics
- development of preparation techniques
- increasing the lateral resolution
- measuring zone plate efficiencies
